This product was designed to create more space in the engine compartment. Combining two reservoirs (windshield washer fluid and coolant overflow) into a single component frees up space for intercooler tube placement, easier maintenance, access to the engine, and durability. A sight glass tube allows you to monitor the coolant level.
TIG-welded aluminum construction. Black powder-coat finish.
Installation instructions.
Fits all 2002-2021 Subaru WRX and WRX STI sedan models. Does not fit dual-pump wagon/hatch models.
